My cat has loved eating this dry food for the past 4 years. I recently bought this product, online, and, when I received it, I noticed that the shape of the kibble was entirely different. It used to be round, now it's rectangular with a waist. My cat won't eat it. I spoke with an Advance consultant at Mars today and she assured me that the formulation hadn't changed, just the shape. If the formulation is the same, the odour is the same, then my cat would still love to eat it, regardless of the shape. I won't buy this product again!
